Oval gear flow meters are simple and robust. They operate by interlocking two oval gears, offset by 90 degrees, inside the meter housing which are then rotated by the flowing media. They are very rugged and designed to operate in very harsh environments. Accuracy is maintained irrespective of temperature, viscosity change, or flow pulsation. It's not unusual to see these meters perform in the field for 30 to 40 years.
